The Big Three: Data Analyst, Data scientist, and Data Engineer
The Big Three: Data Analyst, Data scientist, and Data Engineer
1) Data Analyst
Average salary: $75,068 (plus an average $2,500 yearly cash bonus) This job is usually seen as an "entry level" in the data science industry, but this does not mean that all data analysts are rookies. A data analyst's foremost duty is to analyze business or business data and report conclusions to other divisions. The data analyst might be asked to analyze revenue data from a recent marketing campaign to search for its strengths and weaknesses. It would first need to view the data, potentially clean it, and then do some statistical research to address the critical business questions and present the findings. As for anything else, analysts usually work for several teams within an organization, but research teams may work with a new one from time to time; the work may be to analyze business metrics one month and help the CEO discover why the company has expanded the next. In your position as a data scientist, you will be given business problems to address rather than be forced to mine any patterns from your data. Career prospects: Data analyst is a general concept that covers a wide range of jobs, but your career path is reasonably open-ended.
One popular next step is developing your data science skills, mostly emphasizing machine learning, and applying for a job as a data scientist. Alternatively, if you're more involved in software creation, network engineering, and helping create a full data pipeline, you might consider a job as a data engineer. Any data analyst with programming experience can often advance to more general developer positions. If you stick with data research, several businesses employ senior data analysts. At bigger organizations with data departments, you should also dream about working toward management positions if you're interested in learning management skills.
2) Data scientist
Average salary: $121,674 (plus stock options) Since they're often called "data scientists," they usually accomplish the same activities as data analysts. These data scientists normally use machine learning methods to make precise predictions based on previous observations. Data scientists have greater autonomy to explore different hypotheses and do tests on their data because it is managed. Resource constraints do not limit the data. That data is more flexible because it allows them to discover new patterns and phenomena more easily. To become a data scientist, you will be expected to evaluate the possible impact a shift in business policy may have on your organization's finances. It will take a lot of effort (on the part of the project's administrators and researchers) to gather, clean, and visualize the data, and for the machine learning to be trained so that it can provide potential projections based on past data. Career prospects: An entry-level job title that pays you more than $15,000 a year could very well be called a senior-level role because there are still opportunities for higher pay. If you, as a data scientist, advance to that level, although you might indeed to have a particular role in machine learning, which increases your pay, you might also plan to do more testing, which increases your compensation. Or you should think of a lead data scientist as a management position that includes more data science and management duties than an alternative. If you wish to optimize profits, you might strive for C-level executive data jobs, like chief data officer (CISO) positions, which do not entail large quantities of day-to-day work with data. They are suitable for those with management aptitudes.
3) Data Engineer
Average salary: $129,609 (plus an average $5,000 yearly cash bonus) A data engineer is responsible for the company's data technology. There is a much lower need for data processing on their side, so they must master a lot more programming. In an organization with a data team and a data pipeline, the data engineer is tasked with making the pipelines accessible to the different departments and responsive to departments in the various analytics areas, such as marketing and research and development. They may also be responsible for constructing and retrieving facilities necessary for storing and accessing old records. Career prospects: A data engineer may use their talents to move into many software development fields by gaining additional knowledge. There is also the opportunity to advance and take on an engineering or project manager's job outside of your current position.
